This document provides installation and operational instructions for the Sanela SLW 01NK and SLW 01NKX automatic toilet flushing units. These units are designed for pressured water systems and require a 24 V DC power supply. Proper installation and adherence to safety instructions are essential for correct operation.
Installation
Before installation, ensure you have read the attached safety instructions. The unit must be installed in a wall-mounted configuration. Ensure the water pressure is between 0.1 and 0.6 MPa and that the sieve dimension is ≤ 90 µm. The power supply must be constant and not connected behind a light switch.
- Turn off the power supply.
- Prepare the wall recess according to the dimensions provided (146 mm x 153 mm).
- Connect the 24 V DC power supply cables (brown = positive, white = negative).
- Install the flushing unit into the wall recess.
- Secure the cover plate.
Operation and Settings
The unit operates automatically based on radar detection. The detection range is 0.3 - 0.7 m. The flushing duration can be adjusted using the SANELA Control application or the SLD 03 remote control. Factory settings for the long flush are 5 seconds, and for the short flush, 2 seconds. Note that changing the long flush duration will proportionally change the short flush duration.
Water Flow Adjustment
The water flow can be adjusted manually. Locate the adjustment screw on the valve and turn it to increase or decrease the flow as needed.
Maintenance
Regular maintenance is recommended. Ensure the unit remains under constant voltage for proper function. For technical support or troubleshooting, contact your installation company or visit www.sanela.cz/podpora.
